DESCRIPTION OF RELATED ART

With the emergence of smart phones in recent years, the demand forminiature camera lens is increasing day by day, but the photosensitivedevices of general camera lens are no other than Charge Coupled Device(CCD) or Complementary metal-Oxide Semiconductor Sensor (CMOS sensor),and as the progress of the semiconductor manufacturing technology makesthe pixel size of the photosensitive devices shrink, coupled with thecurrent development trend of electronic products being that theirfunctions should be better and their shape should be thin and small,miniature camera lens with good imaging quality therefor has become amainstream in the market. In order to obtain better imaging quality, thelens that is traditionally equipped in mobile phone cameras adopts athree-piece or four-piece lens structure.
